Class - Sport bike

The Buell XB9 is a series of sport bikes that was made by Buell Motorcycle Company in the United States.
Specifications
The XB9 is powered by a Harley-Davidson 45° V-twin four-stroke engine, with a total displacement of 984 cm³, air and oil cooled and a 10:1 compression ratio. Lubrication is dry sump, the exhaust passes under the engine with a 2 into 1 layout. Distribution takes place via two valves controlled by pushrods and rocker arms with hydraulic valve lifter and hydraulic valve clearance compensation. Powering it is an electronic fuel injection system, with a 45mm throttle body. The engine is assisted by a 5-speed gearbox which transfers power through a toothed belt final drive.
Unlike the Buell XB12 series models introduced in 2004 which have a larger powerplant cubic capacity of 219 cc, the engine has a slightly shorter stroke. This gives the XB9 a higher engine speed, approximately 1000 rpm higher.
Versions
In 2002, the first evolution of the bike was introduced, the Firebolt XB9R, a version with a semi-fairing. Then came the 'Lightning XB9S, a naked version with a small fairing and a shorter rear frame, inspired by the previous S1 Lightning and X1 Lightning models.
At the end of 2004, the Lightning CityX XB9SX arrived, a version with motocross-style elements (handlebar, handguards, protective grille placed on the headlight) and a 92 HP engine at 7500 rpm.
